SHADE m AUTO HEAD-LAMPS.

Specification of Letters Patent. Patented A 17 1920 Application filed0mm 31. 1919. Serial m). 334.711.

To all whom it may concern:

Be it known that I, F RANK E. DAVIS, a citizen of the United States,residing at Bremerton, in the county of Kitsap and State of Vashington,have invented new and useful Improvements in Shades for Auto Head-Lamps,of which the following is a specification;

This invention relates to automobile head lamps and has for its objectthe provision of a shield attachment engageable upon a head lamp andprovided with a plurality of vanes or fins so arranged as to preventblinding of the drivers of approaching automobiles while yet permittingadequate illumination of the roadway.

An important object is the provision of a shield of this character whichis detach- 1 l' ably engageable upon a head lamp and which is providedat its upper portion with a plurality of parallel vanes which extenddownwardly in an inclined direction and which is provided at its lowerportion with a plurality of-vans which are radial with respect to thecenter of the source of light, that is they coincide in directionwiththe direction of the rays of light.

7 An additional object is the provision of a device of this characterwhich will be simple and inexpensive in manufacture, highly efficientand durable in use, eflicient in service, and a general improvement inthe art.

\Vith the above and other objects and advantages in view the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawing inwhich Fig. 1 is a side elevation of a head lamp equipped with my device,

Fig. 2 isa front elevation, and Fig. 3 is a vertical longitudinalsectlonal view.

Referring more particularly to the drawing, the letter A designates anautomobile.

head lamp of ordinary construction having an incandescent bulb B as itssource of light, though it will be understood that as far as theinvention is concerned, the source of light might be an acetylene gasburner.

In carrying out my invention, I provide a shield which comprises acircular band 10 of a size to engage against the front of a lamp A andthis band carries a plurality of spring fingers 11 inwardly curved attheir outer ends, as shown at 12, for engagement with the flange Cusually provided on head lamps and often forming the door .framethereof.

secured transversely of the upper portion of the band 10 are vanes orfins "13 which are parallel, asshown, and secured within the lowerportion of the band are trans versely disposed blades or fins 14; Thevanes or fins 13 areinclined downwardly and forwardly so as to deflectlight from said source B onto,the roadway while not permitting the raysof light to extend upwardly. The vanes or blades 14 are also inclineddownwardly except that instead of being parallel they are radial withrespect. to the center of the 'bulb B or the source of light. All thesevanes are formed preferably of tin-or other suitable thin material andare preferably painted black upon their upper sides.

In the use of my shield it will be seen that rays of light emanatingfrom the source B will strike against the blades or vanes 13' and bedeflected thereby downwardly in an inclined direction onto the roadwayand the rays of light emanating from the source will pass directlybetween the various blades most communities, will be eliminated whilenot in any way sacrificing efiicient illumination of the roadway.

While I have shown and described the preferred embodiment of myinvention it is of course to be understood that I reserve the right tomake such changes in the form,

construction, and arrangementof parts as will not depart. from thespirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. An attachment for automobile. head lamps comprising a circular banddetachably engaged upon the front of a head lamp, a plurality oftransverse forwardly and downwardly inclined parallel blades within theupper portion of said band, and a plurality .of other downwardly andforwardly inclined blades within the lower portion of 14 while the raysof light emanating from said band, said last named blades being andforwardly inclined blades within the radial with respect to the centerof the source lower portion of said band, said last named of light ofthe lamp. blades being radial with respect to the cen- 2. A shieldattachment for automobile ter of the source of light of the lamp, said 5head lamps comprising a circular band at blades being painted black upontheir upper 15 tachment engaged upon the front of the surfaces andhaving their under surfaces head lamp, a plurality of transverseforpolished. wardly and downwardly inclined parallel In testimonywhereof I affix my signature. blades within the upper portion of said 110 band, and a plurality of other downwardly v FRANK E.
